Arm's ready-made chip designs challenge Marvell's custom silicon lead in AI data centers.

Arm Holdings has introduced ready-made chip blueprints and a finished AGI CPU that offer hyperscalers a shortcut, potentially reducing demand for Marvell's custom chip designs. Arm's AGI CPU demand exceeds $2 billion, though supply constraints limit near-term sales, while Marvell posted record revenue driven by data center sales and strong AI-related bookings. Arm's lower gross margins on AGI CPUs could pressure Marvell, which relies on custom chips and complementary products like optics and switching. Investors will watch upcoming earnings for AGI CPU margin details and Marvell's custom chip growth to see who will dominate the AI data center market.

As of Oct 23, 2026 20:02 WIB, Arm Holdings trades at USD 210.78 with a modest 0.32% gain on Pluang, while Marvell Technology is priced slightly higher at USD 223.76, up 0.13%. Despite Arm's strong AGI CPU demand, Marvell's stock shows resilience supported by its record revenue and AI-related bookings. Pluang data shows a higher sell activity for Marvell at 80% compared to Arm's 67%, highlighting differing investor sentiment as the AI data center market competition unfolds.
